Patented Aug. 27, 1946 UNITED STATES PATENT OFFICE MATRIX FILLER Andrew W. Davis, Madison, Ill. Appiication May 15, 1945, Serial No. 593,950 4 Claims. (01. 1 2 63) the time'period for converting the machine, to

a minimum.

Another object of the invention is to provide a sectional matrix filler which when positioned on the matrix roll, will be securely held against displacement.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Figure 1 is an elevational view of a counter stiffener forming machine, illustrating a matrix filler, constructed in accordance with the invention, as positioned on the matrix roll thereof.

Figure 2 is a plan view thereof.

Figure 3 is a vertical sectional view through the machine.

Figure 4 is a perspective view illustrating the matrix roll sectionsas separated, and one of the filler sections used on the matrix roll.

Referring to the drawings in detail, the reference character 5 designates the table of a counter stiffener skiving machine, which is provided with an opening through which the feed roll 6 extends, A

the feed roll being rotated b suitable means not shown, whereby the counter stiffeners are fed through the machine.

The reference character 1 indicates the knife holder block, the fixed knife supported thereby, being indicated by the reference character 8, the knife being adjustable by means of the set screw 9 which is shown as extended into a threaded opening formed in the knife holder block 1, the main portion of the screw being disposed within the elongated opening I!) formed in the fixed knife '8.

The matrix roll is indicated by the reference character II, and is mounted on the shaft l2, the matrix roll being provided with flanges i3 which are disposed directly opposite to each other, the flanges having cut-out portions l pro viding shoulders l5 adjacent to the ends thereof.

The matrix fillers embody semicircular mernbers 16 which are constructed of suitable material, preferably plastic material, the members H5 being curved so that they will accurately fit the curvature of the matrix roll I I. As clearly shown by Fig. 4 of the drawings, one end of each matrix filler section It is formed with cut-out portions adjacent to one of its ends, providing an extension H, the extensions" of the sections of the matrix filler, being positioned within the cut-out portions Id of the matrix roll. The edges of the matrix filler sections are beveled, as shown by Fig. 4 of the drawings, and these beveled edges are adapted to cooperate with the beveled surfaces of the disks l8 and IS. The disk I8 is secured to the shaft l2, and when the matrix fillers are positioned, one end of each (filler section is positioned so that it contacts with the beveled surface of the disk l8. The disk I9 is now slid into position over the opposite beveled edges of the sections of the fillers, and the nuts 20 are operated to force the disk l9 into gripping relation with the matrix filler sections. Thus it will be seen that dueto this construction, the filler sections may be readily and easily removed or positioned. While I have shown and described the disk H! as attached to the shaft 12, it is to be understood that the disk may, if desired, be constructed as an integral part of shaft l2.

It will of course be understood that the surface of the matrix filler sections are ground out to form recesses indicated at 2!, to fit various sizes and designs of counter stiffener thereby permit ting the counter to move into the recesses which are formed to skive the desired portion of the counter stiifeners.

Should it be desired to remove the matrix fillers and replace them with filler having recesses for skiving counter stiffener blanks of a larger or smaller size or design, the filler blocks may be readily removed and replaced with filler blocks which will form the required size of stiffener blank, eliminating the necessity of replacing the entire matrix roll, to make the change.

From the foregoing it is believed that due to the construction shown and described, the utility of applicants invention will be apparent, and that a further detailed disclosure as to the use of the device is unnecessary.

What is claimed is:

1. The combination with a matrix. roll and matrix roll shaft of a counter stifiener skiving r 3 7 machine, of a. matrix filler comprising wide semicircular: filler sections, adapted to fit around the matrix r011, said matrix r011 having cut-out por-i tions, extensions on the ends of the filler sections adapted to fit into the cut-out portions of thematrix roll, and disks fitted on the matrix roll shaftadapted to engage said filler sections, se-,

curing the filler sections on the'matrix roll.

2. The combination with a matrix roll and matrix roll shaft of a counter stiffener skiving machine, of a matrix filler comprising wide semi-f circular filler sections, adapted to fit around the, r matrix roll, a stationary disk mounted on the: shaft and having a concaved surface, said filler sections having beveled edges adapted to fit into the concaved surface of the stationary disk, and

a movable disk having a concaved surface-adapt ends of the sections to the matrix roll, the edges of the filler sections being-beveled, a stationary disk having a concaved surface fitted on the shaft and adapted to fit over the beveled edges of the filler sections, at one side of the filler sections,

a movable disk having a concaved surface adapted to fit'over theopposite side edges of the filler sections, and a nut on the matrix roll shaft adapted to engage the movable disk, securing the movable disk in engagement with the filler sec- 3 tions.

ed to fit over the opposite beveled edge of r the" matrix filler, securingthe matrix filler section on the matrix r011.

3. The combination'with a matrix roll and matrixroll shaft of a counter stifiener skiving machine, of a matrix filler comprising wide semicircular filler sections, means for securing the 4, The combination with a matrix roll and matrix r011 shaft of a counter stiffener skiving ANDREW W. DAVIS.
